By using the DWM1200 winding machine to detect the consistency of the three-phase windings (>99%), and conducting no-load/load tests at the Dekai certified testing station, a repair plan will be provided within 24 hours after locating the noise source.

The ZGS11 box-type transformer adopts an IP54 protection design, with a built-in temperature sensor for real-time monitoring.  Combined with a full vacuum oil injection process, it ensures stable insulation oil performance, allowing for uninterrupted power supply 24 hours a day even in extreme environments.

Using HEDRICH vacuum casting technology to reconstruct the coil structure, and conducting full-wave/chopped-wave lightning impulse tests at the KT testing station, ensures that the partial discharge value is ≤5pC.  A full life-cycle quality traceability system is also upgraded simultaneously.

Applying the S22 oil-immersed transformer drying process reduces no-load losses by 15%, and combining it with the SH15 amorphous alloy series saves 70% energy.  Energy efficiency audits are conducted simultaneously to track carbon footprint and assist in applying for energy-saving subsidies.

A 24-hour fault response mechanism is activated. Emergency repairs are carried out through a full vacuum oil injection quantitative control system.  A fault analysis report and improvement plan will be provided within 48 hours by the "Dekai + CNAS" dual-certified laboratory.
